Students Conduct Successful Static Fire Test of a New Rocket Engine in Preparation for P: "Following the recent launch of their 1000 lbf thrust ablative annular aerospike engine onboard Prospector-2 two months earlier, the CALVEIN team accomplished yet another milestone with the successful second flight of a liquid-propellant aerospike engine on Sunday, Dec. 7. This flight applied lessons-learned from the previous one to fully demonstrate the performance of the liquid propellant, ablative aerospike engine.....
.....The aerospike engine suffered none of the sub-optimal performance observed during the first flight (Sept. 21) thanks to a small modification made to the outer ring prior to laying up the ablative material. The aerospike engine demonstrated a clean burn-to-propellant-depletion and both the payload deployment and single-parachute recovery systems appeared to have functioned nominally.

Due to the wind and small launch rail inclination (4 deg. from vertical), the vehicle weather-vaned upon leaving the 57-ft launch rail before then entering a straight, stable trajectory in the direction towards the Koehn dry lake bed reaching an altitude greater than 4000 ft. The P4 then returned to the ground under full parachute, with all systems still functional."

Artist turns animals into everyday objects

Ananova - A Chilean artist is making a name for herself with an exhibition in which stuffed animals are transformed into household objects. Artworks on display include a chick turned into a lamp, and 'sheep bag' - a lamb carcass fitted with handles. Artist Caterina Purdy says her exhibition at the Experimental Arts Centre in Santiago is intended to be humorous but also makes a serious point. She told Las Ultimas Noticias online: 'It is possible to see my work as something scary, but I find it beautiful. 'There is also irony and humour in my objects as well as a criticism of the way animals are treated by society.'"

Josh Nimoy @ ITP - BallDroppings

Josh Nimoy @ ITP - BallDroppings : "BallDroppings is an addicting and noisy play-toy. It can also be seen as an emergence game. My brother Marc takes this software seriously as an audio-visual performance instrument. Balls fall from the top of the screen and bounce off the lines you are drawing with the mouse. The balls make a percussive and melodic sound, whose pitch depends on how fast the ball is moving when it hits the line."
